Recipe Overview

  • Yield: Large Batch (approx. 800ml - 1L)

  • Prep time: 20 minutes

  • Cook time: 30–45 minutes

  • Storage: Up to 1 year (Vacuum-sealed/Frozen)

Ingredients

Part 1: The Base (For Blending)

  • 300g shallots

  • 200g garlic

  • 100g turmeric (peeled and grilled)

  • 1 tsp salt

  • 1 tsp white pepper

  • 200ml water

Part 2: The Aromatics & Oil

  • 200ml canola oil

  • 40g ginger (thinly sliced)

  • 40g galangal (thinly sliced)

  • 3 lemongrass stalks (bruised)

  • 5 lime leaves

  • 3 bay leaves

  • 1 tsp mushroom powder

Cooking Instructions

  1. Prepare the Base: Place all ingredients from Part 1 into a high-speed blender. Process until the mixture is a completely smooth, vibrant paste.

  2. Reduce the Moisture: Transfer the blended paste into a heavy-bottomed pot or wok. Cook over medium-to-low heat, stirring occasionally. Continue until the water has evaporated and the paste has thickened significantly.

  3. Fry and Infuse: Once the paste is thick, pour in the canola oil and add the ginger, galangal, lemongrass, lime leaves, and bay leaves.

  4. Sauté to Perfection: Continue cooking for approximately 5 minutes. You will know it is ready when the "raw" smell of the turmeric is gone, the oil starts to separate from the paste, and the aroma is deeply fragrant.

  5. Final Seasoning: Stir in the mushroom powder. Remove from heat and allow the paste to cool completely before storing.

How to Use & Store

  • Immediate Use: Use as a marinade for grilled seafood and poultry, or as a base for Soto Ayam, Gulai, and Nasi Kuning.

  • Freezing: For best results, portion the paste into vacuum bags or airtight containers. It stays fresh in the freezer for up to one year.

Pro Tip: Grilling the turmeric before blending (as specified in Part 1) is the secret to removing the bitter "earthy" notes and unlocking a deeper, smoky sweetness in your Bumbu.
